So I've run into a situation recently (thankfully regarding a team where I'm not the coach) where a parent indicated to the head coach (and to the other parents) that his son wouldn't be coming to a couple games on an upcoming Saturday because he felt it was too far for "exhibition" games and he wanted his son to be rested for a league game on Sunday.

This is wrong to me on a number of levels. It's one thing if a parent wants to approach the coach and voice a concern that perhaps there are too many games (a potentially very valid concern).
